Show answers and working
1. -4
Subtracting (-6) is the same as adding 6. -10 + 6 = -4
2. -2
Subtracting 8 is the same as adding -8. 6 + (-8) = -2
3. -7
Subtracting (-3) is the same as adding 3. -10 + 3 = -7
4. -8
Subtracting 3 is the same as adding -3. -5 + (-3) = -8
5. -10
Multiply the sizes: 10 × 1 = 10. Same signs give positive, different signs give negative. Answer: -10
6. -28
Start at -15 on a number line. Move 13 left. You land on -28.
7. -180
Multiply the sizes: 15 × 12 = 180. Same signs give positive, different signs give negative. Answer: -180
8. 11
Start at 19 on a number line. Move 8 left. You land on 11.
9. -12
Subtracting 13 is the same as adding -13. 1 + (-13) = -12
10. 31
Start at 30 on a number line. Move 1 right. You land on 31.
11. -4
Start at 21 on a number line. Move 25 left. You land on -4.
12. -16
Subtracting 29 is the same as adding -29. 13 + (-29) = -16
Worked examples
-3 + 4 = ?

- Answer: 1
-1 × 7 = ?
- Multiply the sizes: 1 × 7 = 7.
- Same signs give positive, different signs give negative.
- Answer: -7
- Answer: -7
21 + 9 = ?

Common mistakes
What learners typically get wrong, and how to fix it.
Thinks −8 is bigger than −3.
Correction: Further left on the number line means smaller.
Treats − (−4) as −4.
Correction: Two minus signs together become a plus.
Teacher tips
- · Use a vertical number line like a thermometer.
Parent tips
- · Compare winter temperatures from the weather forecast.
Real-life applications
